I really want to see Luan and Luna bonding in an episode since we've never seen a full episode with the two interacting with each other and no Deep Cuts doesn't count.
I also want to see Luan and Benny go to the school dance
Another one I really want to see Luan prank the 8th grade bullies Anderson, Pablo and Taylor on April Fool's Day to punish them for beating up on her brother and his friends.
